ANKARA, Turkey (AP) — Turkey is advising its citizens to avoid all non-essential travel to Lebanon following the kidnapping of two Turkish nationals there.

The Turkish Foreign Ministry on Friday also urged Turks already in Lebanon to take "all kinds of precautions" for their safety.

The travel advisory was issued hours after the country confirmed that a second Turk — a truck driver — was abducted in Lebanon on Thursday.

On Wednesday, members of a powerful Shiite Muslim clan said they had kidnapped more than 20 Syrian nationals and a Turk in retaliation for the abduction of their relative in Syria this week.

The abductions have raised concerns that Syria's civil war is spilling into Lebanon.
